Pros:

- Changes majority of sounds

- Certain weapons have a more desired "kick" to them (I.e. Combat shotgun, or more commonly known as Spas, Silenced SMG, SCAR or Rifle_desert,

Cons:

- Pistols don't sound too well, however that is excused. The rest is not.

- Certain weapons have been deprived of their "kick", otherwise deafened. (I.e. Pump shotgun/Chrome Shotgun, SMG, Tactical Shotgun or The Benelli, Rifle or M16, Hunting rifle)

- AK47 Doesn't seem to have changed whatsoever?

- No grenade launcher sound change? WHAT?! >:( Blasphemy.

- The Military sniper sounds unchanged, and still weak as ever. You may be shooting it but it doesn't feel satisfying whatsoever.

Conclusion:

Let me start this off by saying that this review is based off the below video, I have not downloaded nor tested this addon in any form, and so have not had the chance to detect warping or audio glitches.    

Overall, it does what it is meant to do, that is to replace the majority of the weapons in l4d2's sounds. It did this. I'm judging the overall quality to my tastes, and I will say that although some of the sounds are detrimental to it, and don't give the user, or in this case, me, satisfaction wielding. Regardless, there are some specks of hope for not all of the sounds are horrid or depriving. Look around for more resources to pull from, keep swapping sounds to see what makes the user WANT to use that gun because it sounds kick ass, and continue to do that to every weapon. This pack has potential, but currently, needs work. 

Good day ~ Ted
